# How to configure the frequency of measurements and messages
One of the most common configurations a user would like to change is the frequency of the measurements taken by the sensor and the frequency of the messages the end user receives. To accomplish this, the user must generate a downlink (which can be done using the [NEON configurator](https://neon-configurator.twtg.io/)) and send it to the device via their LoRa Network Server (LNS).
### NEON TS Protocol v2
On the **Application Configuration** tab, the field **Temperature Measurement Interval Seconds** defines how often the sensor takes a measurement, and the field **Periodic Event Message Interval** establishes after how many measurements the transmitter sends data over LoRa.
Thus, the frequency of the messages is determined by **Temperature Measurement Interval Seconds** multiplied by **Periodic Event Message Interval**. For example, above the **Temperature Measurement Interval Seconds** is 900 seconds and the **Periodic Event Message Interval** is 16, which means that the frequency of the data messages will be 14400 seconds, equivalent to 4 hours.
